looks like a really high quality product.
My bearings need to be replaced, I think that I am going to buy some of these.

As I recall, the Hope web site has a faq that says the grooving on the freehub is to be expected and does not effect performance. I’ve got grooving on a set of Hope XC hubs, after intially getting established the grooves have not grown, and I don’t notice any impact on performance. The grooves may make it a little more difficult to remove the cassette, mine stuck a little last time I was removing it, but I’m not sure if it was the grooves.

Nice thorough review about the Pro2 hubs. But…

What you, and so many other reviewers of the Pro2 20mm front hubs fail to mention, is that it is the actual inner race of the bearing that lie directly on the 20mm thru axle. The little rings on the outside are there just for sideways spacing. To be sure that all users are able to mount their wheels, the bearing race has to have manufacturing tolerances that lie on the outside of the nominal 20mm and the axle has to have tolerances that lie on the inside of the nominal 20mm. This translates to play between the hub and the axle.

In my case, where I mated a 20mm Pro2 front hub to a RockShox Pike, this play translated to +/- 1.5mm of sideways play at the rim. Tightening the Maxle didn’t improve the situation as this does not remove the above mentioned play. So my brake disc sometimes sang in left turns and sometimes there were a slight sound, like worn shock bushing, when you lifted the bike. Tightening the axle real hard removed this sound, but my brakes reminded me that the play was still there.

DT Swiss, Chris King and other 20mm hubs have a design with a center tube, that take up play against the bearings. This tube again digs into the fork outers when you tighten the thru axle, removing the play between the hub and the thru-axle/fork assembly.
